CONTAINER Chester M. MacChesney, Chicago, Ill., assignor to Acme Steel Company, Chicago, Ill., a corporation of Illinois Application Decemberv31, 1934,l Serial No. 759,840 8 Claims.A (Cl. 229-517) This invention relates to improvements in containers and method of forming thesame and its primary purpose is to provide an' improved collapsible container embodying a novel bottom construction by which the bottom wall of the containerA is united with an annular nonmetallic wall. The principal parts of containers of this type are customarily made of paper, fibreboard or similar non-metallic material, including an annular collapsible wall which is shipped in its Vcollapsed state to the point of use where it is assembled with the other parts of thev container by the user. -For purposes of economy-in construction, it is desirable that the annular wall and the bottom wall of such a container be formed of non-metallic material and that these parts becapable of being united by the user with the use of a connecting member which may be readily put in place without the use of any auxiliary fastening means. It is therefore the principal object of the present invention to provide an improved container of this type comprising a collapsible annular Wall and a bottom wall, both formed of non-metallic material, in combination with a series of fastening devices which are assembled onthe annular w-all at the place of manufacture and which are adapted to form an interlocking engagement with an annular metallic rim. placed over the lower endof the annular wall by the user for the purposeof reenforcing this wall and supporting the bottom wall. Another object of the invention to provide a collapsible container comprising an annular non-metallic wall-in combination with a cup-shaped bottom wall adapted to t over the annular wall, a bottom disk tting within the annular wall, and an annular metallic rim having a flange adapted to snap over a series of attaching devices carried by the annular wall and having a' part extending beneath and supporting said cup-shaped bottom member. Another object of the invention is to provide an improved method of forming a container comprising the steps of forming a collapsible cylindrical non-metallic wall, attaching to said wall an annular series of outwardly extending projections adjacent its lower end, expanding said collapsible wall within an annular metallic rim having an inwardly extending annular ange at;- its lower edge, and an annular inturned angeV around its upper edge located above said projections when said wall is expanded, and then forcing downwardly within said annular wall Ato a position within said lower in turned flange a disk adapted to hold said annular wall in a condition wherein said projections interlock with the upper i-nturned ange on said rim. Still another object of the invention isto provide an improved method offorming a container comprising the steps of forming an annular noncollapsible metallic wall, securing to said wall adjacent its lower end an annular series of outwardly extending projections, forming an annular metallic rim having an inturned flange at its lower edge and another inturned ange at its upper edge, placing within said rim on said lower flange a cup-shaped non-metallic member,

then placing within said rim and Within said cup-shaped member the lower portion of said annular non-metallic wall and expanding said 4wall, and then placing within the lower end of said annular wall a member adapted to hold said annular wall in expanded condition wherein said projections interlock with the rupper angc of said rim. Other objects relate to various details of construction, and to features of the improved method of forming the container, which will appear more fully hereinafter.

The nature of the invention will be understood from the 'following specification taken with the accompanying drawing, in which certain em- `bodiments of the improved container land one example of the improved method of forming it are illustrated. In the drawing,

Fig. l shows a side elevation o-f a complete container embodying the features ofthe present invention;

Fig. 2 shows a bottom plan view of the container illustrated in Fig. -1;

Fig. 3 is a perspectvevview of the cup-shaped bottom member which is adapted to receive the lower end of the annular wall'of the container illustrated in Fig. l;

, Fig. 4 is a perspective view of the bottom wall or disk which is adapted to iit within the anlthe annular wall of the container;

Fig. 7 is a sectional view similar to that of Fig. 7, showing a modified form of construe.-A

tion `of the attaching devices; and

Fig. 8 is another sectional view similar to that of Fig. 6, showing another arrangement of Cit the attaching devices carried by the annular wall.

As illustrated in the drawing, the improved container I is shown as comprising a cylindrical non-metallic wall II, formed preferably from a sheet of paper or similar material, which has its ends overlapped or secured together by glue or other fastening means. After being thus formed, this cylindrical shell is ordinarily collapsed and a group of them are packed together in a bale or bundle and shipped to the consumer, who then expands the annular wall and assembles it with other parts of the structure, including `a conventional top I3 and a bottom comprising th-e improved vannular metallic wall I4 and other associated parts forming the bottom structure of the improved container of the present invention. The annular non-metallic wall II is provided at the place of manufacture with a series of attaching devices I5 which project outwardly from the outer surface of the annular wall and which are preferably in the form of metallic staples having outer projecting portions I5n lying in contact with the outer surface vof the annular wall, as shown in Fig. 6, and having side arms I5b which project through the annular wall and are then reversely bent or clinched as shown at I5c with their extremities ld again entering the annular wall in an outward direction. These attaching devices I5 form an annular series around the wall II and are spaced a suitable distance above the lower end of the wall II so that they lie slightly below the upper edge of the metallic rim I4.

Therim I4 is formed from a flat strip of steel or the like which is bent in the form of a complete annular rim with its ends overlapped and secured together by rivets, spot welds or the like.

This rim comprises a cylindrical body portion |42# having along its lower edge an upwardly and inwardly inclined transversely corrugated ange I4b, and having along its upper edge an inwardly and downwardly turned annular flange |40. These flanges are preferably formed on the body portion of the rim during the process of manufacture and prior to the operation of securing the overlapping ends of the rim together. The lower flange I4b of the metal rim is adapted to support a cup-shaped bottom member I 6 of pa.- per, breboard, or other non-metallic material which is preferably pressed in a hot condition into the shape shown in the drawing, where it is shown as comprising a circular horizontal portion IGS and an annular upturned flange |61. The lower end of the annular wall II is adapted to t closely within the ilange I6b of the member I6 and, when so assembled within the rim I4, the outwardly projecting attaching devices I5 are adapted to lie just beneath the inturned flange I4c of the metallic rim so that the attaching devices interlock with'the ange |4s and hold the cup-shaped bottom member 4I6 in proper the collapsible wall II may rst be expanded 4within the cup-shaped member I6 and then these members may be inserted `within the me- Wall .I la.

tallic rim I4, or the cup-shaped member I6 may be placed within the rim I4 with the portion I6a thereof resting on the annular flange I4,b of the rim and then the annular wall II may be placed within the cup-shaped member I6 and within the rim II and then expanded until it engages the ups'tanding flange IID and until the attaching devices I5 occupy positions just beneath the inturned ange I4c on the rim I4. If the annular wall II is expanded within the cup-shaped member before the rim I4 is applied, the rim may be slipped upwardly over the members II n and I6 until the annular inclined flange I4 snaps over the attaching devices I5 into' interlocking engagement therewith. When the other parts have been assembled so that the ilange I4c occupies a position above the outwardly projecting portionsof the attaching devices I5, the bottom disk II is inserted within the annular wall until it rests upon the portion I6 of the cup-shaped member. 'I'his disk is of the same diameter as the inner diameter of the wall II and serves not only tostrengthen and reenforce the bottom of the container but also to hold the annular wall II in its expanded condition wherein the attaching devices I5 are maintained in interlocking engagement with the ilange I4c of the rim.

Instead of employing staples of the usual form for forming the attaching deVices,-as illustrated in Fig. 6, the modiied construction illustrated in Fig. 7 may be employed. In this form, the annular wall IIa of the container is provided with an annular series of staples 'I8 each of which has an outer portion I 3a lying in contact with the annular wall and provided at its middle point `with an outwardly curved hump or projection I8b which'increases the projection of the attaching device beyond the annular Wall as compared with the form illustrated in Fig. 6. Each staple I8'has side arms I8c which extend through the annular wall and these side walls are reversely bent or clinched as shown at I8d with their extremities I8e directed outwardly into the Another modification of the attaching devices is illustrated in Fig. 8, where the annular wall IIb is shown as being provided vwith attaching devices each having the form of a staple I9, similar to the form illustrated in Fig. 6, except that the staples are reversed-with the transverse portions I!)a thereof lying in contact with the inner surface of the annular wall and their side arms |91 projecting outwardly through the annular Wall. These side armsare reversely bent or clinched o n the outer side lof the container wall, forming curved outwardly extending projections Illc which are adapted to interlock with the flange I4 of the rim. These projecting portions,Av terminate in' extremities I9d which project'inwardlyinto the annular wall IIb.

Although one form of the improved container, with modifications of certain portions thereof, has been illustrated in conjunction with the -lllustration of one example of forming the container, it will be understood that the invention lmay be embodied in various forms of construction and may be practiced in various ways coming within the scope of the appended claims.
